# `Raxol.MCP.Supervisor`
[🔗](https://github.com/DROOdotFOO/raxol/blob/v2.8.0/lib/raxol/mcp/supervisor.ex#L1)

Supervision tree for the MCP subsystem.

Starts the client's shared table owner, the Registry and the Server. The
stdio transport is NOT started automatically (it takes over stdin/stdout) --
use `mix mcp.server` or start it explicitly.

## Children (rest_for_one)

1. `Raxol.MCP.Client.Tables` -- the per-origin era verdicts and circuit
   breakers the HTTP client transport shares between clients. First, so that
   a Registry or Server restart does not discard state that belongs to
   neither of them (ADR-0037 decision 2).
2. `Raxol.MCP.Registry` -- ETS-backed tool/resource store
3. `Raxol.MCP.Server` -- transport-agnostic message router
